Potassium (K) is an essential mineral element for plant. K in soil is the main source for plant growth, and it is taken up by plant through mass flow, diffusion and root interception. The different K transference mode are affected by many factors. In this paper we reviewed the factors which affect the movement of K in soil, including physical, chemical and biological factors, summarized the effects of soil moisture, texture, bulk densities, temperature, pH, accompany ions, K concentration and plant characteristics on the movement of K in soil. Finally, we prospected the focus research on the movement of K in soil.
